Forty-five percent of all blood donated in the United States is type 0. Type 0 blood is essential for emergencies where there is no time for determining the blood type of victims because type 0 blood can be used for everyone. Type 0 blood is unique in that it is compatible with blood of all types: any recipient, regardless of blood type, can be given it. But precisely because of this special usefulness, type 0 blood is chronically in short supply.


If the statements in the passage above are true, which of the following must also be true?

(A) The special usefulness· of type 0 blood lies in the fact that it matches the blood type of most people.
(B) Supplies of type 0 blood are continuously so low that type 0 blood is unavailable for emergencies, where its usefulness would be greatest.
(C) Forty-five percent of the total population of the United States has type 0 blood, which makes type 0 the most common blood type.
(D) Any decision to give blood of any type other than 0 needs to be based on knowledge of the recipient's blood type.
(E) Type 0 blood is the only blood that cannot be typed as fast as needed in emergencies.

(A) The special usefulness of type 0 blood lies in the fact that it matches the blood type of most people

Incorrect: It doesn't matches the blood type of most people but is compatible with blood of all types. Even if one uses matches interchangeability with compatible, most vs all distinction still prevails.


(B) Supplies of type 0 blood are continuously so low that type 0 blood is unavailable for emergencies, where its usefulness would be greatest.

Incorrect: Supply low or not can not be inferred. What can be inferred is that supply cannot meet the demand as type 0 can be used irrespective of recipient's blood type.



(C) Forty-five percent of the total population of the United States has type 0 blood, which makes type 0 the most common blood type.

Incorrect: 45% of all blood donated is of type A.

(D) Any decision to give blood of any type other than 0 needs to be based on knowledge of the recipient's blood type.

Correct: It is mentioned that Type 0 blood can be given to any recipient regardless of his/her blood type. It is also mentioned that this application of type 0 is unique. Thus, decision to given other blood types can not be made in absence of knowledge of recipient's blood type

(E) Type 0 blood is the only blood that cannot be typed as fast as needed in emergencies.

The passage does mention that "type 0 blood is chronically in short supply. " Isn't that proof for B? What trumped me though was that there is no way to determine that quantity is so low that even emergency demands are not being met. Thus eliminated B for the same reason.
